Use of mapping strategies
TODO : Mapping strategies refer to Power networks/Guidelines#Mapping strategies. They are used for a methodical improvement of the OSM database. Once you have fully applied a strategy in this country, you should add or update your name, the date, the strategy, and a comment below. This way, other users can see whether it is worthwhile to carry out further investigations.
